Hi there!
Since the sum of all angles in any triangle always adds up to 180 degrees, we can calculate this and solve for x.
4x + x + x = 180°
6x = 180
180 ÷ 6 = x
x = 30
So, now we know that x is 30°.
Hope this helps!
"Sum" tells us it's an addition problem:
One term is 12 and the other is 9/x
SO
The expression is:
12+9/x
36
Add all the sides up
15+15=30
3+3=6
30+6=36
I think the answer Is C I hope it helped you
